Application. March 23, 1946, Serial No. 656,689

This invention relates to shoes and to their construction, and has (foran object to provide a method wherein no lasting allowance for the upperis necessary though, if desired, the outer may be pulled onto the lastin order to shape it to the last.

In accordance with this invention, therefore, a thin, flexible innersoleis secured about its margin to the shoe lining, and this assembly isslip lasted, after which the outer with a secur ing strip or welt ispulled over and secured, and the shoe is then completed.

Further objects and advantages will appear from a description of certainembodiments of the invention shown in the accompanying drawings in whichFigure l is an inverted plan view of the shoe parts in condition forslip lasting.

Figure 2 is a detail sectional view on line 2--2 of Figure 1.

Figure 3 is a view similar to Figure 2, showing the outer lasted.

Figure 4 is a view similar to Figure 3, but showing further steps in themaking of the shoe.

Figures 5 and 6 are views similar to Figures 2 and 3, respectively, butshowing a modification.

Figures 7 and 8 are views similar to Figures 5 and 6, respectively, butshowing another mod-ification.

Figure 9 is a view similar to Figures 2 and 5, but showing still anothermodification.

Figure 10 is a view similar to Figure 9, but showing the shoe in a moreadvanced condition.

Referring first to Figures 1 to 4, a flexible innersole l is marginallysecured to the lining 2 of a lined shoe upper, as by a line of stitchingat 3. The marginal portion of the outer, which is at this time unsecuredto the innersole, previously had applied thereto a welt strip 4. Asshown in Figure 2, the welt strip has its outer face turned toward theouter face of the outer 5 and'is secured to this outer in overlyingrelation as by the stitching 6. After the lining and innersole marginshave been secured together, the shoe is slip lasted, the last beingshown at l in Figures 3 and 4. Thereafter the outer is lasted over,bringing the welt 4 into partly underlying relation substantiallyparallel to the innersole I and having its outer margin extendingoutwardly from the margin of the outer 5 as shown in Fi ure 3. Suchlasting may be effected, if desired, by'engaging suitable clamp membersbetween the outer edge of the welt strip and the upper in accordancewith the well known pre-welt method of lasting. While the upper is heldin this but 3 Claims. (Cl. 12-142) condition, either by cement securingthe inwardly turned edge portion Ill of the outer, or by maintaining thelasting mechanism in lasting position, a filler H may beinserted againstthe lower face of the innersole I to bring the outer surface of the soleto substantially the transverse plane of the lower face of the welt 4and an outersole I2 is then applied and secured to the welt 4 as byoutersole stitches I4. This construction provides a shoe having theappearance of a welt shoe, but permits the shoe to be initially lastedby the slip lasting method and permits the outer to be pulled onto the.last.

'Instead of forming the marginal strip applied to the outer as a welt,it may be otherwise formed as i1lustrated, for example, in Figures 5 to10.

,Referring first to Figures 5 and 6, instead of the welt strip 4, a thinflexible strip 28 may be employed, secured to the marginal portion ofthe outer as by thestitching 2!. When the outer is pulled over, the freeedge of this strip 20 may be brought around to enclose the outer face ofthe stitching 2| as shown in Figure 6, bridging over its margin togetherwith the margin of the outer 5, and it may be brought in to overlie andbe cemented to the innersole l as shown in Figure 6. This provides abeaded eifect to the lower edge of the upper. An outersole may then beapplied against the in-turned edge portion of the strip 20, using afiller, if desired, or necessary, between the outersole and innersole.

In Figures '7 and 8, a strip 22 of canvas, or the like, is secured tothe lower margin of the outer 5 as by stitches 23. This strip 22 is of amore or less porous material, such as canvas, to which cement willreadily adhere without requiring any roughing operation as is usuallynecessary when the grain face of leather is being conditioned to takecement. This strip 22 forms substantially a lasting allowancecontinuation of the outer, and it may be grasped by the pulling pinchersor other suitable mechanism by which the. outer may be pulled over andthe strip laid down against the face of the innersole i where it may becemented as shown in Figure 8. This construction permits the cutting ofthe upper without lasting allowance, and provides a surface to take thecement which requires no roughing which would be required with lastingallowances on upper materials of many types. The outersole may then besecured against the innersole and the strip 22, with or without a filleras may be necessary, depending upon the thickness of the strip 22, andother shoemaking fantors.

A third method of employing a marginal strip for the outer isillustrated in Figures 9 and 10. In these figures, the outer 5a is shownas provided with a lasting allowance, and to its margin is secured, asby stitching 25, a narrow marginal strip '26. When the shoe is to belasted a flexible non-extensible cord or wire 21 (see Figure 10) may beengaged between the strip 25 and the outer 5a outwardly of the stitching25, so that when this strand .21 .is pulled at oppositevends, the outermay be pulled inwardly around the lining and innersole into the lastedposition shown in Figure 10, the lasting allowance portion of the outerbeing brought in against the outer margin of the innersole. The

parts may be secured in this position as by they use of a temporarycement, after which the strand 2! may be removed. The outer surface ofthe outer 5a may then be roughed in the usual manner, this roughingalsoremoving the strip 25 which has served its intended purpose infacilitating the lasting in of the outer. The parts being thusconditioned, an outersole -may be cemented to the inturn-ed margin ofthe outer,

with or without a filler between it and the innersole, as may be founddesirable.

From the foregoing description of certain embodiments of this inventionit should be evident to those skilled in the art that various furtherchanges and'modifications might be made without departing'from thespirit or scope of this invention.

I claim:

1. The method of making a shoe, which comprises marginally securing aninnersole to the lining of a shoe upper, the outer of which is pro--vided with a marginal strip on its outer face, slip lasting, applying aflexible non-extensible strand about said outer outwardly of andengaging said strip, pulling the outerover said last by pulling oppositeend portions of said strand in the proper directions, securing thepulled over outer and removing said strand, and thereafter completingthe shoe.

1 2. The method of making a shoe, which comouter and removing saidstrand, r emoving said strip, and thereafter completing the shoe.

3. The method of making a shoe, which comprises marginally securing aninnersole to the lining of a shoe upper, the outer of which is providedwith a marginal strip on its outer face, slip lasting, applying aflexible non-extensible strand about said outer outwardly of and en- 4gaging said strip, pulling the outer over the last by pulling oppositeend portions of said strand in the proper directions, securing thepulled over outer and removing the strand, roughing the outer surface ofthe in-turned margin of the outer and removing the marginal strip by theroughing operation, and cementing an outersole to said roughened margin.
